Ok so a couple weeks ago, I was at my dad's house (I don't live with him) and I downloaded music from their Mac (different iTunes account) onto my phone. I downloaded about 200 songs.

Just bought a used iPhone 4 from ebay?

The product says: You are bidding on an excellent condition Apple iPhone 4 - 8GB - White (AT&T)

The front screen has a small crack at the top right corner and the bottom right corner, but is in good condition otherwise. The back is in great condition with only some small scuffing. The metal rim is in good condition except for some small scratching. The volume, home and lock buttons all work perfectly. Overall the phone is in great condition if you don't mind the cracks in the front screen.

This phone has been reset and has a clean ESN, so its ready to go. It also has iCloud lock turned off. We ship all items within 24 hours, good luck bidding and don't hesitate to ask any questions.

I want to use it on Metro Pcs. How can i do that or if the phone does not allow me to do that what other carrier beside AT&T would work? Maybe straight talk?

Iphone Texting Internationally?

So I will be going overseas to England and maybe some other places in Europe. I do not have any international plan on my phone, so once I head over my iPhone 5 will be in "Airplane Mode". Is there any texting app I can use that doesn't use Wi-Fi so i can stay connected with my girlfriend? I don't know how often I will be able to use Wi-Fi. Also do those mobile Wi-Fi things (ex. Verizon Jetpack) do they need to have cellular to work? Or do they work fine on Airplane mode?

Best way to design an iPhone app?

I'm looking to design an iPhone app. I have no experience coding or anything but thankfully the design will be very simple.

All I need is an easy way to make a menu, have four options in that menu, then 50 more options for each of those options. Essentially just folders inside folders. Then I need the user to pick values 1-100 and be able to multiply some numbers depending on the values they put.

What's the best way to be able to design an app like this? Please give me names of programs I should try to use.
