This is my first phone in years after the Samsung D600 but I have a few questions for you guys and gals here 1. I understand that there is no security passcode lock for certain areas of the UI (e.g. Mail, Contact List) but is there an App that offers such a feature? 2. For those on T-Mobile, what are the 3G speeds like using the G2 Touch? Is it generally on par, slower or faster than the speeds offered by Orange? 3. Is the default browser Google based or is it Opera? If it's not Opera, how does it compare to Opera Mini? 4. Would you recommend a screen protector and if so which one? 5. When you buy Apps from the Marketplace, will you be able to redownload those Apps if you decide to upgrade the SD card or is there a backup feature?
