Ok, so I'm kinda tech savvy, and I tried my first jailbreak/unlock today. Long story short, I'm spent. I have been working at It all day, learning all of these new technical words and processes. I managed to run into and fix all sorts of problems, but I am at a dead end. -using an AT&T-13.0 iphone4-GSM ios6 -Firmware 4.12.02 -Jailbroke using snowbreeze, -hacktivated it, and I reboot using ibooty (cause Im tethered -whatever that means.) -Unlock by activating Ultra Snow fixer for 6x via ipare.com -activated ulltrasnow via dev team. -Downloaded TetherMe and made the proper changes in Data Network-MMS from tmobile.com -Filed down my sim card to fit perfectly into sim slot WITHOUT TOUCHING THE GOLD(before anyone asks). At this point I cannot connect to any data service, and even though I changed the Data Network settings to t-mobile settings, that still does not changed my carrier, so I still get "no service" or "invalid sim" any tips at this point??? I figured that I still have not fully unlocked my phone, so I read aobut this "SAM" method, but I have no "t-mobile unlock" ticket/file backup of my own. based off the info I provided; will uploading a t-mobile ticket via redsnow fix my problem? if so, does anyone have a file or know where to get one?
