I purchased a iPhone 3GS off of Craigslist. It was locked to AT&T and I wanted to get it to work with Red Pocket Mobile. A few days after getting it, the phone froze up and would not power on. Sent a RMA to apple since it was covered still. Received phone today, thought id check to see if my Red Pocket Mobile SIM would work right out of the box, it did. Got Data working via http://www.unlockit.co.nz website. However my MMS still doesn't work. Did research and found that the issue is I need to get TeatherMe app from Cydia. Which requires my phone to be JB. I do not want to JB/unlock if I dont have to. For one, my phone appears to be Unlocked already as my SIM worked right out of the box (however, iTunes did not mention anything about it being unlocked when I plugged it in). My baseband is the 5.16.05, which is unlockable w/o upgrading to iPad baseband. Since my phone is the iPhone 3GS 8GB (with serial showing manufact date of Jan 2012) I do not want to upgrade to iPad Baseband as it will brick my hardware. If I restored my iPhone in iTunes, will it still work with my Red Pocket? I assume so since it worked right out of the box, so I assume its factory unlocked and restoring would keep my unlock still. Also, if I do JB, will it keep my unlock status as well? I had my first iPhone i got off of CL Jailbroken before it crashed. (Sry for asking what may be a newbie question. This is my first Apple product, and had an RMA already due to issues getting it to work with Red Pocket. Phone works with it now, so I am hesitant to modify it to ensure it keeps working. But I would like to be able to send MMS pictures to family of my kid). I did several google searching of the entire web, but most sites came up with unlocking software/services. Found out how to fix my MMS issue, but want to ensure by JB'n my iPhone it will not kick out my Red Pocket Voice/text/Data stuff.
