Hi Jeff. You could use App Backup & Restore
to backup apps to your SD Card and then restore them. The only drawback is it won't backup the data with the app. You could also try My Backup
but I don't know if it will backup data with the app unless you are rooted. I know its a pain, but it may be best to start with a fresh formatted sd card and reinstall apps.
Cases and screen protectors are more a personal choice. I wouldn't say they are required, but I use them to protect my investment from scratches and for a higher resale value.
Its on the pricey side, but I love my Seido case and holster
. I can't really talk about the kickstand because I've never used it much. It works fine in landscape mode but does seem fragile.
If you want inexpensive, I used a case like this Fishbone
for my Optimus V and really like it.
Just one thing to remember about cases, make sure its for the T-Mobile GS2. With so many different carriers, not all the holes may line up.
The GS2's glass is scratch resistant but not scratch proof. I used these screen protectors
. They come in a 5-pack and work just fine.
Again, cases and screen protectors are a personal choice so just look around and see what you like and read the reviews.
Enjoy your new GS2. It's a great phone.
