Hi, 1st post here so here it goes I've a 3gs 32gb iOS 4.1 jailbroken using greenpois0n. I've just come back from a short trip to Dublin. I've been running a Travel guide for Dublin along with some other programs inc some games. When I first arrived I was automatically using 02, but then it moved and stayed on Vodafone IE. My usual carrier is Orange. I had switched off 3g data & roaming etc, but connected to the hotel wifi. Anyway, over the period over the few days my apps took longer and longer to work and start running. I thought the jb had affected my phone, slowing it down. I was going to restore it when I arrived home, but once I got back to the UK the phone started running at normal speed. Now the travel guide I was using used the gps location service and didnt need to be connected to any data, but it was strange that it (may have) slowed everything else down. Maybe the continued use of the program caused a data overload in its cache?? I didnt want to delete it as I was still using it. Anyway else had this experience??
