I would like to get my app data from my iPod touch OS 4.0 to my unlocked iPhone 3GS 3.1.3 firmware. I can right click the iPhone in iTunes and ‘restore from backup’ and choose the iPod touch backup. iTunes says it will not mess with firmware, just music, contacts, etc. If I go through with this, will I lose my unlock? Can I lose Unlock of my iPhone 3GS 3.1.3 firmware if I transfer my app data from my iPod touch OS 4.0 to iPhone? If so, can I re-unlock to 3.1.3? Please help. Thanks.
