hey guys...just bought myself a V3i. planning to upgrade the software. which one should i use (the latest one)? and i see that there are 2 kinds of V3i...the i-tunes one and the non i-tunes one. im not really sure what's my V3i and if let say i flash it with the wrong firmware...(non itunes flashed with an i-tunes one)...could it brick my phone? thanks in advance
