Im thinking about getting a new phone for christmas and don't know if i should get an iphone (probably the 3gs because of price) or an Android phone (particularly the Captivate) A big concern, and why im leaning towards the iphone, is for music. I also want this phone to replace my ipod and know the iphone has an ipod, itunes store and all that. I have about 11gb's of music i want to put on, so would the 16gb be enough with all the apps and other stuff as well? Also once you create a plan, say i chose the 450 minutes per month or whatever it is, can i later upgrade that to the 700 or unlimited options? Same thing with the data pack and texting?
