Hi all, Currently I'm using an iPhone 3GS with baseband 6.15.00 running on a Cydia jailbreak and unlock to use a T-Mo SIM card in my phone. I recently read about ordering an unlock from eBay where you could send in your IMEI number and get your phone unlocked within 24 hours. Has anyone used a service like this previously? Also, would I have to downgrade my baseband and/or remove the jailbreak to get my phone "officially" unlocked? I don't really know how to go about doing this as I purchased my phone with the jailbreak+unlock already installed. Thanks!
