Tempt me away from an iPhone 5...

[C.A.R.]

So my 'upgrade' is due this December, but because of the level of demand and the lack of available tarriffs I can't get an iPhone 5 to replace my iPhone 4...

There are however lots of other smartphones available on my current package as upgrades, some free and some with an up-front payment.

Thing is, I've never even considered anything else so I have no idea what to look out for.

I use my phone for-
Business calls and personal calls
Lots of texting
Checking different email accounts and sending replies to emails
Photographs (I'm constantly taking pics of the baby!)
Music

Basically the main functions you would expect I guess, but I don't really want to wait an extra 6 months to get a slightly different iPhone...

Also the iPhone has a bit of a reputation of not actually being as good as other smartphones so I would prefer something more powerful...
