Under the circumstances, my phone has been painfully slow. I recently jailbroke and upgraded my iPhone 3g to 4.0. Currently, Sbsettings is running actively along with "Phone" as the only process listed. I only have 35 MB of memory free, making it difficult to even browse the web. Is this normal? Also, I don't recall allowing multi-tasking on 4.0 when jailbreaking, but I may have on accident as I had trouble getting the phone into mode for jailbreaking and may have accidentally checked multi-tasking or left it checked after restarting the program. How do I deactivate multi-tasking? How do I tell if it is active on my phone? I assume it is as many tasks are listed through SBSettings at times. How can I reduce overall memory usage to eliminate lag-time and closure of applications? Thanks for any and all help.
