I have rooted my phone and installed the new modaco rom. I have an 8gb class 4 sdcard. Here are my questions: Is it wise to put my apps on the sdcard and run it from there even though its only a class 4 and not the 6 everyone says? Also, with the new rom I find it a bit laggy at times, for example I find I have to hold down the icon longer before I can move it around on the homepage or other pages. Any ideas on these?
