I have a relatively new Aria that I have been considering rooting. Several reasons. 1. Not impressed with the onboard memory and would like to delete bloatware such as Peep, AT&T Maps/Navigator/Hot Spots, Footprints, Friend Stream, IM, Latitude, and a few others. A few of those apps keep showing up in my ATK list, so I'd like to just get rid of them, as I have no intent to use them...why let them wreck my RAM? 2. Speed. I've read enough forum posts to believe that my device will run selected apps faster. Make it so. 3. Use MicroSD card for apps. Hate to be limited to the internal capacity. I expect to partition the new SD card, 1GB dedicated to apps. New card likely to be 8GB. Here are the questions... 1. I'll be getting a new SD card before the rooting begins. How important is the whole Class 2/4/6 thing. Is Class 4 good enough? 2. If I simply swap out the SD card with a new one before the root, what would I lose besides the photos, movies, music that I have manually transferred to the existing SD card? 3. How do I go about backing up the phone for restoration if the rooting thing doesn't work out? 4. What apps/functionality will I find in the phone after the rooting? 5. Is there a list of apps/files that should not be deleted after the rooting? 6. What is all this "flasing ROM" talk about? How do I chose what I should be flashing? What are the differences and does my device model matter in this decision?
