Can you upgrade 2g on tmobile to work with 4.0 software

[disneyfun1]

using 3.1.3 software on my iphone on tmobile, can you put 4.0 software on it as of yet or should i have it done at all?

Nope... 2G only support up to 3.1.3

There is a custom firmware for 3.1.3 on ip3g and ip2g which acts as a 4.0 ios.. Just email a random letter or some **** to [email protected] and it autoreplies with their custom firmwares..

Ps.those are zeros in the d00r
