Im in the process of buying a new SD Card for my phone. I have read that class 4 is reccomended/necessary for Apps2SDand moving the davlik to sd card.. My question is will getting a higher class actually benefit on the Ascend besides transferring files to/from sd card (basically will the phone itself run quicker with a Class 4 vs Class 6 vs Class 10 as its only as fast as the slowest part) Thanks
