I have a jail broken 32G 3G iPad running 4.2.1 . Recently, some apps crash and sometimes the homepage looks messes up - like it should be portrait, but apps show in landscape. Respringing will generally fix that.
I have tried soft restart ( 2 button reset), re syching in ITunes, downloading a new app from iTunes, unauthorizing and then reauthorizing my ITunes PC, deleting and then re downloading the troublesome apps - (that did fix ONE app)
Not sure what to try next. This crashing may have followed a recent update from Cydia or maybe its just a coincidence. I think I have plenty of memory left, or perhaps it is a ram problem... Not sure how to tell.
Thanks for any suggestions.
