Switching from AT&T iPhone to htc inspire on straight talk?

I'm currently using an unlocked AT&T iPhone with straight talk, I bought an AT&T sim card. I'm going to switch to an unlocked AT&T htc inspire. Do I have to buy another straight talk AT&T sim card? Or can I just use the same one? I do not want to switch phone numbers!

Memory help on the iPhone 4?

I have an iPhone 4 and it keeps telling me I'm running low or out of memory. I only have 41 songs and 2 apps I've personally downloaded. (Not joking I counted.) the apps are Facebook and Instagram. Can anybody tell me what i can do to fix this? Or why those 2 things take so much memory?

Which android should I get for my iphone 4s?

I got an iPhone 5 from the droid bionic. The bionic was my first smartphone and I was so overwhelmed. But after getting the hang of android I loves it. I went to iPhone 5 to taste the iOS ecosystem and iPhone build quality. I love it. But I just hate that iPhone is so limited. I can't even attach a resume to the email app. I don't wanna download third party apps. It's so limited I hate it.

Anyways

I wanted to give my dad my iPhone 5. Sell his iphome 4s and buy a galaxy nexus. I want the nexus for the pure google experience. I could also get the rAAzrrm for about the same I sell the 4s but it seems smaller and not pure google.

So should I sell the iPhone 4S for a nexus? I hear some complains on radio and battery but I'm almost always driving so I always charge the phone.
