After getting another brand new 2G iPhone, I can not decide what firmware to put on this 2G iPhone and JB and Unlock it to use with my tmobile SIM. I JB and Unlocked my wife 2G with quickpwn and put 2.2.1 on it and she still has it, using it without any issues at all, it was quick and painless process to JB the phone. When I bought myself a 2G and try to do redsnow 0.8 using Shift restore 3.0 and then JB and Unlocking with 3.0 FW file it did not work, phone JB but SIM was not seen, iphone and itunes did not see my SIM, still said no SIM. I could not find a solution for it, so now with this new phone I want some suggestions of what route to take.

I have a 2 year old Tmobile SIM card, I read somewhere that older SIM card could have been the issue why it did not see it, since I did everything right. But I read that many people also had same issues and kept 2.2.1 on their 2G phones, and that some who did upgrade and JB and Unlocked the 2G iPhones with 3.0 FW had issues with phone freezing up, bad battery life, etc.. What do you think?!

I installed 8.0.2 iTunes to JB with quickpwn, plugged in iphone, itunes tells me I need 8.2 or higher itunes to see the iphone, my T-Mobile SIM was inside of iphone. Does that mean this iphone has 3.0 FW on it now?! Since 3.0 FW needs 8.2 itunes to see the phone and also do redsn0w JB?! I know with another iphone 2G I had I had an issue to downgrade from 3.0 to 2.2.1 when my redsn0w JB did not work and 2G did not see my T-Mobile SIM. Is there a code on iphone in emergency screen I can type in to see what firmware is on theis Brand NEW iPhone before i proceed with Shift restore and JB process?!
