You cannot flash it since at&t is a GSM or "chip" phone it can only be flashed to other carriers that are GSM such as T Mobile or telcel, and cricket is a CDMA which can be flashed from phones such as sprint, verizon and alltel.
Only if the phone has been unlocked from all networks. If it's 'tied' to cricket, the T-Mobile SIM won't work in it.
i do not think so since they use different networks..
no, not unless Cricket has changed their phone. You see T mobile has a SIM card and the only other companies that have that is AT&T . You can used an unlocked AT&T phone on T mobile or vice versa but not cricket
YES!
You cannot use a T Mobile phone on Cricket network. T Mobile is a GSM carrier while Cricket is a CDMA/iDen carrier. These two technologies are not compatible with each other as they operate on different frequencies. So a T Mobile phone could not support the frequency of the Cricket network even if you have an unlocked phone.

You can't use an ATT LG Cf360 on Cricket because it runs on a different frequency, which the ATT phones do not support.
Cricket Communications uses CDMA, so their phones do not have SIM cards.
Yes you can flash a Samsung Galaxy S4cricket phone T mobile on cellunlock.net.
there aren't. but i was told by a representative that you can order online and activate your cricket phone over the phone and use it.
Verizon, AT&T, Cricket, pretty much anywhere.
For an Android phone, Cricket, AT&T and Sprint have the best ones. they range in price depending if you get a contract or not. cricket does not offer contracts and their android phones are around 100 dollars.
