iPhone 4

• If you can and have enough money you should definitely get Two. Some ferrets can lonely and stressed if things to do a day and another ferret friend can give both ferrets exercise and comfort. if you spend the day at work or school the ferrets need each other and get very attached!!!!

• Not necessarily. As pets, you can keep one, and it will be perfectly content if you have plenty of time to play with your ferret as they crave human interaction, two can keep each other occupied if you don't have a lot of time for your ferret.

• So the answer to your question is: 'No, they don't have to be in pairs - but they would prefer it.'

• Yes - if they're already friends. Two ferrets provide company for one another. Our two constantly snuggle and play together and one on its own would need more attention from us. However, buying two ferrets who do not know or like one another needs more care.

• Ferrets are not pack animals. But, due to domestication, they retain more juvenile characteristics (cf.s dogs similar behaviour to wolf puppies). They view their companion ferret as a litter-mate.

• Yes, ferrets do like to be in pairs but they can be just as happy by themselves. If you are someone who is busy and can't let your ferret out of the cage as much as you are supposed to then you should consider getting another ferret. But you still have to remember that even if you have two ferrets, they still have to be let out to run around and play together. Even if you are thinking about getting another ferret you also have to remember that you may have a ferret that may not get along with another ferret so you may be his only friend.

Review: Superior Sim Ultra + For iPhone 4 Modemfirmware 04.12.09 with Ios 7.0.4 SIM hack

For much of the last two years time, even the manufacturer of these SIM hack products acknowledge that their product is no longer needed; so it was quite a surprise when Superior Solution announced that they have something that will unlock the iPhone 4 BB 04.12.09 with Ios 7.0.4 . Contrary to conspiracy theories, they withheld onto the product because:

• Initial production cost is high, they risk losing a lot of their investment should the dev team come up with a software unlock that does the same job if not better, before they were able to recover their cost.
• The exploit they used is not without serious problems, hence they were reluctant to produce it until there seems to be no alternatives coming for a while.
• The exploit they used is very simple, provided you have the tools and skill, details to follow...

I have made a mistake earlier by calling it TurboSIM and it is not. @MuscleNerd reminded me of the correct term "SIM interposer", since it sits electrically between the SIM card and baseband hardware to perform a classic.

How did It Work?

SIM card holds many different types of information, but the part most involved with carrier lock is the IMSI number, which is a unique code that corresponds to your account in the mobile carrier's database.

A sample IMSI might look like this

310 150 987654321

The first two segments are known as Mobile Country Code (MCC) and Mobile Network Code (MNC) respectively, and in the example above the IMSI indicate the SIM is from USA (310) AT&T (150).

When the iPhone baseband is loaded into memory, it checks the MCC and MNC against its own network lock state stored in the seczone. If the combination is allowed, the cell radio is activated and vice versa.

The earliest iPhone baseband revisions only check IMSI twice following a restart, therefore it is very easy to spoof information in order to bypass the check. Never theless, the baseband was soon updated to validate SIM more aggressively and the method no longer works.

To guard against eavesdropping that plagued pre-GSM cellular networks, the initial connection to a network does not only involve IMSI, but a 4-byte TMSI to identify each handset before IMSI is sent. The base station recognises the IMSI as one of their users and replies with a nonce (RAND) to the handset, where is signed with a 128bit key (Ki, stored encrypted on the SIM) and sent back. The network checks the string against their own result using the same RAND and Ki and allows the device to register if the two value matches.

You see, the IMSI is only sent once and never directly involved with authentication; as long as your key is valid, you will be able to get service. This is exactly what the various SIM hacks where a fake IMSI is sent along with the correct key. In our case, the IMSI is invalid but some network proceed to the next step anyway - I will explain this in detail later.

Partial Revival

Apparently somebody figured out that while the i4 baseband has been patched to prevent test IMSI from working, it is still possible to force activate the baseband using the emergency dialer.

After that, it is relatively the same trick all over again. Let's see what it does at each step.

You will need to use the SIM tray supplied and file your MicroSIM slightly to accommodate the EEPROM chip.

Installing the Superior Sim Ultra +.

The phone will search for signal, comes up with no service and finally settling on this "one bar" icon. At this stage the sim interposer is passing the parameters from the SIM as is.

Dial 112 and hang up after the call is connected. The emergency call overrides the network lock and activates the cell radio. The network issues a TMSI for your real IMSI.

Note: This Step No Appear Normally This step When I Do When I Not Got Sinals In Bars.

Toggle Airplane mod On/Off. Once the interposer senses Airplane mod, it transiently blocks electrical connection between the phone and the SIM (hence it will show "No SIM card installed")

The signal bars appear, we are safe:-) The network is able to register you again because the TMSI you obtained earlier is still valid, and the IMSI is not checked again.
