How should I replace my iphone 4 with a 5?

My carrier is verizon, i've had my iphone 4 white for almost 2 years? It says 13.7 gb capacity too. I want to upgrade to a iphone 5, but should i try to sell my 4 and buy a 5, or find somewhere to trade, or just go directly through verizon? Or other options? For my first 2 options, where would be legitimate places to buy/sell/or trade?

If I were I would get Android.

Just go directly through Verizon. It will be simpler and less hassle. It costs about 100 dollars more, but it's worth it. They will transfer everything onto your new iPhone 5 and some stores offer a new case with a trade-in. You can keep your number, pictures and everything. If you don't want to spend that, sell it on eBay or some other site. You can still transfer everything, but you will have to do it yourself after backing your iPhone up and restoring it. My advice - do it through Verizon. Hope this helps.

I would wait until Apple release the Iphone 5s as this is where you see improvements in the device. A 4 is till good but if I were you i would hold onto it for the time being.

I think it would be more affordable to go through Verizon. Usually they will be able let you purchase a subsidized phone if you are near the end of your contract. You would be able to upgrade to the iPhone 5 with less hassle. It is not as affordable to sell the iPhone 4 and then purchase the iPhone 5.It will also cause more stress to find a legitimate seller who will not scam you. It will be wise to contact Verizon and let them carry out the upgrade for you.
