[PLEASE HELP] I'm due for a phone upgrade - Android or iPhone or A Nother?

[Porter's Dad]

Just got a call saying I'm able to get an upgrade on my phone. I've got a iPhone 3G, I think (it's the basic one), and I really do like it and an upgrade to iPhone 4 would be fine - but the sales rep really sold the Android to me (and I'll be getting it cheaper too).

Now, before anyone says "google it, b*tch", I'd just like to say that BSL has always been very helpful when I've had these sorts of questions, so hopefully you guys can come through for me again

Thanks, people.
