Seidio Innocase Surface with a Casemate screen protector. I like this case because doesn't add too much bulk and once it's on the phone feels so much more solid. Not that the phone was flimsy to begin with... i just wanted the added protection without feeling like I have a brick in my pocket. That's the reason why I haven't picked up a Casemate Pop even though it offers the most protection of all the cases that I've looked into.
I bought a silicon gel case off ebay not the dollar cheapies but it was about 6.00 it works well for my shirt pocket. Thought about getting the innocase surfce and holster combo found on ebay for 35.99 but havent done it yet waiting to see what new mango phones are coming dont want to spend the dough if I am getting a different phone.
Yesterday I dropped my phone for the first time. After a long night studying and 2 hours of sleep, I picked it up to shut off the alarm and I dropped it (not much, 2' at most). Thank God I had some kind of protection on it!
