I recently upgraded to Froyo via Kies (on T-Mobile) to:
I have noticed that the phone performance has improved significantly following this upgrade but still noticing some lag on the general use and certain applications. I was looking into some ways that i can improve my phone further? Is there better firmwares that i can flash to the phone? Lag fixes i can apply? Rooting?
If any experts out there could help me with this then it would be greatly appreciated!
