I think I originally used Absinthe v0.3. It seemed to run fine for a few weeks but then I started having a few apps randomly crash. Most notably, Safari. Sometimes opening a link in a new tab would crash, sometimes creating a new bookmark folder would cause a crash. I also had the BiteSMS trial (6.2 beta X), Waze GPS, findme, MobileTerminal and Grocery iQ crash (it was always in the Dispatch queue thread).
Since there are rumors of iOS 5.1 being released soon, I took the time last Friday to start fresh and re-jailbreak with Absinthe v0.4 and load back all of my jailbreak tweaks a few at a time to see if I could find an issue.
It ran fine all weekend (no crashes) with a good amount of my previous tweaks installed. Last night I decided to try out the BiteSMS trial again (v6.2 beta 7) and this morning I had my first new Safari crash. I had just opened Safari and double tapped (zoom to fit) when it crashed.
When I originally jailbroke, I ran it for a few weeks before trying BiteSMS. I don't remember exactly when I first installed it, but it was sometime around when I first started to see apps crashing. It's not looking good for me and BiteSMS, although this new crash happened in a different thread, Webcore: CFNetwork Loader, so who really knows what is causing it??? I'm going to leave BiteSMS installed for a few more days and see what happens. If I see more crashes, I guess I'll remove it and see what happens next. Atleast BiteSMS offered a free trial so I could test this stuff out.
