I currently have an iPhone 5 on 6.0.2 on T-Mobile. I'm sort of stuck on whether or not I should update to 6.1.4 or keep this firmware, and heres the reason why. I'm currently jailbroken and I have all the useful little widgets and utilities making my everyday iOS life easier (sbsettings, 5 item dock, custom multitask tray where i can adjust brightness etc.) and all those really useful things. But along with that I only get 3G connectivity on T-Mobile, and my phone tends to crash a lot....always respringing and apps randomly crashing and closing whenever I'm using it... Update to iOS 6.1.4 I would assume that all the glitching, crashing, respringing, etc would finally cease and I would be able to get my 4G/LTE connectivity, but then I lose all of the jailbroken goodness I currently have Should I update to 6.1.4 and lose my jailbreak? Is there any sort of app in the appstore where I can have easier access to things like brightness? Help me out!!
