How do you unlock a samsung boost mobile Android phone?
= Unlock Boost Phone for Nextel Service = Boost cell phones will work with on the Nextel network. However, only very basic functions such as making & receiving calls and receiving text messages will be available. These limited abilities do not meet the needs of many cell phone subscribers.
To unlock available features, you need to have computer cables to attach your phone to computer. Also required are your codeplug (file type RAR - use this link to get Microsoft help - http://multiplexelectronics.home.att.net/moddinginfo.html ) and an RSS program.
To unlock your phone is fairly complicated and you would need to be an advanced computer user. The program you will need to write will depend on your particular phone model and the features or services you require. For those less technical, there are message boards on the internet (ie: cell phone hacks and MP3Car) where experts volunteer to write the programs to unlock phones. Some people choose pay services where they can pay a one time charge for the services they want unlocked.
What is surprising is that Nextel doesn't do a good job of helping subscribers unlock their Boost phones, since this would allow Nextel to sell additional value added services. Unlocking Boost phones allows the phone to download ring tones, applications such as games, walkie-talkie (Moto Talk) and sending text messages and pictures. Not only are these money making ventures for Nextel, the walkie-talkie feature distinguishes Nextel from the other major wireless companies.
Other features that are disabled can change the look and feel of the phone. These include keypad and screen color, keypad lights, inverted LCD and American dialing (555-555-5555). Also, people unlock services which are typically included with most plans including 3-way calling, voice activation dialing, and speaker phones.
Some people unlock their phone to turn off billing charges such as picture and text messaging, to obtain premium service such as widen, which allows you to surf the internet at faster speeds , or access GPS.
One of the strange twists is even if you unlock your phone for some features; Nextel may not provide the service in all markets. This often happens with trying to use your phone as a computer modem, even if widen is turned on.
Whatever you decide, just be careful. Downloading the wrong program could completely disable your phone or you could get caught by Nextel for stealing services.

Invasion of privacy between adults is wrong. No doubt. Even if he's cheating, you're not "right." However, if he IS cheating, then you have a right to know. The following is bold, not sneaky: ask him to SHOW you his cell phone for your own peace of mind. If he accuses you of jealousy, that would be a true statement, and you could admit to that. BUT, you can also tell him that if he cares for you, he will ease your mind by showing you what you want to see. If he has no text messages in there and they have been deleted there is foul play. In that case I would just check his cell phone when you can. If you were married to him, I would check his voice mail. Ask him for his code. If he won't give it to you, kick him, you can't trust him He shouldn't care if there is no lying between you two about other people. But he may want some things to be his own business. If I were you, I would only want a relationship where I wouldn't want to go through his stuff. Actually, he might find it offensive or feel like a small kid if someone was continually keeping track of his stuff. The only reason it would be alright is if you needed a number you both used mutually maybe for an emergency, or to make something more convenient for the both of you. It should be an understood situation, and there should be no question of right or wrong.

How do you unlock a Motorola t-mobile phone?
It's a quote from a different forum: "I have a Motorola C 139 tracphone. I want to know can it be unlocked. I sent it in to a unlock shop and it was sent back saying it can not be unlocked. Here is what they said "We received your phone and tried to unlock it many times but failed.
Unforunately, it cannot be done as
we do not unlock Tracfone handsets. Tracfone modify all their
handset's software to display "Air Tank",
which is exclusively a proprietary feature. Even if the service
provider restriction has been removed, where
a C139 from Cingular or T-Mobile can work immediately with a SIM from
another network, the Tracfone
will not be able to make calls due to empty "Air Tank". Had this been
a normal C139 from any other carriers,
we would have been able to unlock it easily for you"
"The answer that you were given is partially correct. Although you can unlock a tracfone, it wouldn't be worth it due to the software that they use. If you did manage to get it unlocked, it would only work on another network for as many minutes as you had left on the tracfone. After you run out of minutes, the phone would shut off and you would not be able to use it.
In order to fully use the phone on another network, you would have to unlock and reflash the phone after deleting the tracfone software...Not recommended if you are not familiar with reflashing phones."
