Hi all. I'm considering upgrading to the S7, and I'm also wondering if I should go with the unlocked version rather than the T-Mobile version. What's the main differences besides not having T-Mobile software preloaded? When you pay off a phone on T-Mobile, they unlock the phone anyway, so is there any difference between this type of unlock and buying the unlocked version? Also, I use three T-Mobile apps: the main T-Mobile account app, Visual Voicemail, and Mobile Hotspot (for making the phone a WiFi hotspot). The first two I think I can download from the Play Store, but how would I get the Mobile Hotspot app if I buy the unlocked version? Thanks!
