Jailbreak trouble... iOS 7
A little bit of caution, friendos.
I dealt with 2 iPhones and an iPad in the last 2 days that developed serious issues
after the "pwntunes" tweak was installed. pwntunes, essentially, makes it possible to connect an iDevice to a Windows PC and transfer files without iTunes' help. Essentially a pseudo mass storage mode.
The problem: once the devices were connected to a Windows PC, iTunes would no longer recognise the devices. AT ALL. And upon 2nd connection to a PC, Windows no longer recognises the devices, either.
So: I haven't researched the issue, but I'd suggest to avoid pwntunes for now.
Also: CAUTION: this is a repeat, but hey... DO NOT perform a factory reset
ON THE PHONE should your iDevice develop an issue after jailbreaking with Evasion!!!!!!!! REPEAT: do NOT factory reset via Settings => General + Reset!!!!!
Your phone or pad will end up in a boot loop. IF your lucky, nothing will happen - i.e. you waste time with resetting without ANY actual reset happening! But 2 of the 3 devices I saw went into bootloop, and they were not updated over-the-air (a known risk factor).
Reset only via iTunes and restore from a good back-up.
