Hi I have a 3gs with BB 5.16.05 locked to ATT and have NOT jailbroken or unlocked it yet. I was wondering if it's better to downgrade to the iPad BB (using 5.16.00) or to actually go down to 4.1. I've also read you can use 5.13.04. I'm not a tecchie so don't know much about which option is best -- but I'll be using my phone in SE Asia where I will need GPS. (Unless I can use GPS through Wifi instead?) And I'll also be needing to use iCloud, which is only possible on ios5. Can you please help? I really appreciate it. Thank you.
