After a gruesome basketball incident in which my iPhone 5S was rendered unusable, I've used it as an excuse to get a new phone, and I'm making the switch from the cozy pleb shelter of iOS to Android 5.0. Gonna need some help though, I haven't used the OS in very, very long, and when I did, I knew nothing about it. So I've got a few questions.

1. I'm planning on getting the vanilla HTC One. Is there any compelling reason to get any other model?

2. First time switching phones mid-contract. I'm currently on T-Mobile, and the phone I'm looking at is an Unlocked Verizon, which claims to also be unlocked on GSM, which is what T-Mobile uses. Can I trust that claim and what exactly do I have to do to get the phone "activated"?

3. Lastly, and most importantly, having chiefly used iOS for upwards of 5 years, there are some features I would find incredibly hard to do without.

Recommend me replica tweaks/applications of...
• iOS Control Center (which also works in lockscreen)
• An iOS-style keyboard, if possible
• Safari-style browser tweak
• The best NDS and PSP emulators out there, preferably free
