Hello guys, I need some of the suggestions regarding jailbreak and increasing the speed of the device. Here are the details of my device. iPod Touch 2G MC Model 8GB with Model Number MC086ID with iOS 4.0 installed. I applied star jailbreak via jailbreakme.com. I've enabled backgrounding and wallpaper, also applied fix which stated to delete some overlay files to increase the speed. But still the device is slow and hardly runs a single application, and though multitasking is enable, as soon as I start 2nd application, first application automatically gets closed due to the lack of memory I suppose. So here are my questions. 1. Is 4.1 any faster than 4.0? 2. Are there any supposed advantages of enabling multitasking when I can't do it anyways? 3. Is there any proper jailbreak for IPT2G MC on iOS 4.1? If yes, which one? 4. Should I update to 4.1 or just downgrade to 3.1.3 and enjoy the faster speeds? Thanks for reading, hope to get some answers.
