I recently got my old Pantech Burst back to replace my other Pantech Burst. It turns out that they are to different models. I've been trying to download apps that i had on my other one but it either says "your device isn't compatible with this version" or ["blank" could not be downloaded due to an error. (Error retrieving information from server. [RPC:S-3]). I tried updating my phone but that didn't work and neither did just restarting it. I really need help because I'm starting to hate this phone and I might just throw it away and get a new one.
