Great information there, I have always wondered the right way to go about this, thanks for showing me!

Hi There Techatlast,
Interesting Post, There are people who cannot live without their trusty electronic device. Some people even own several ones. After all, who doesn’t love gadgets, especially in this electronic and digital age? It helps people stay connected with family and friends (especially those who live far away), keep them updated in the latest happenings with the use of social media, and helps people keep track of their busy schedules. Sadly, electronic gadgets are always subject to the harsh elements (water, wind, dust) and owners who do not handle them carefully which results in scratches in the casing, dirty keypads and screens with numerous fingerprints.
Good Job!

Hopefully they are working STILL on a version for my phone (HTC HD2) that will work without any major issues. I have seen some ICS versions on the HD2, but those still have mingling problems. I know they use the HD2’s as a “lab rat” when new Android versions come out to see if it can be ported successfully, then they move on to other versions above it.
