Can't get Twitter notifications?

Just got a new iPhone but can't seem to get any Twitter notifications? I already went to my Twitter and enabled the push notifications but I still don't get any! Help!

Do i still have access to my previous iphone backups?

Apple won't replace my phone, unless I do a complete restore (phone is acting crazy), which I did. They told me I can't click restore from backup, and I have to do it as a create a new iphone. Now let's say I get my phone replaced, can I still restore from backup before I did the restore. Do I have access to my previous backups is my question. If so, how would I backup it and pick the backup I want.

IPhone 5, is 16gb okay and iCloud?

I'm thinking of purchasing an iPhone 5, and i'm not sure if 16gb is okay for me? I'm the person who would be taking videos and pictures, but i wouldn't be downloading tv shows or movies (as I have an iPod touch for all that) i like to download apps, but yet again i would only be having my main ones on the Iphone as I have the iPod. I'm just wondering if that would be okay if anyone is like expert on things like this. I'm also wondering about the 'iCloud' has anyone ever had trouble with it and is it hard to use?

Setting up a hotspot on an iPhone?

So I just got this iPhone and I only bought 3gb of data, but since my mom has unlimited data (she was grandfathered), is there a way that I can connect to her phone through Wi-Fi while she's using her 4G while on a road trip? Like ca. I set up a hotspot on her phone and then connect my phone to it? If so, how can we do that?
