Hey guys i asked this a while back but I with evasion out and everything I want to upgrade this 3gs that I have at firmware 5.1.1 now, but I can't get it to read a sim card everything else seems to be working. I was wondering if I updated to 6.1.3 and then used evasion to jailbreak it. or I'm I stick using this as an Ipod. Thanks guys.
