Hello all I've got just a really general query. I've currently been having problems with my galaxy s2. Recently my s2 hasn't been able to detect a sim card inside so I took it back to the store and the guy told me that the device had been jailbroken and that I have somehow fried my network capabilities or something like that . I know I have not jailbroken my s2, but I have jailbroken my ipod (i'm familiar with the process), so I'm wondering is it possible for any app from the google store to jailbreak the phone. Ive downloaded several apps from the store such as Apex launher and poweramp (free version) and I'm wondering have any of these apps broken my phone somehow? Any help would be greatly appreciated.
