I need cellphone help. Iphone 4?

I'm a carrier for Sprint, I have an Iphone 4, 8gb, and I noticed that neither my data or Wi-Fi will download apps as fast as it should. It takes about 20-30 minutes for each app to finish downloading. So yesterday, I took it to MacExperience, an Apple repair shop and got another iPhone as replacement, and this one is doing it too! What could be causing this? Or could it just be Sprint's network. It just doesn't make sense to have two phones in a row doing the same exact thing.

Can you still use a iphone 5 sprint even if it has Invalid Length?

I bought a sprint iphone 5 on craigslist and i tried to unlock with GPP. The original carrier is Sprint but i want it for Net 10. I did the steps right and i got the signal but then loses it and goes to straight no service. So maybe i thought it had a bad esn (blacklisted) so i went to this website checkesnfree.com and it says INVALID LENGTH? They gave me this definition " The amount of characters entered is invalid". What does that mean? Can i still use it? Or is the Gpp not working?

IPhone app installing trouble?

I have the iPhone 4 and whenever I download an app it takes forever to install. The downloading process is quick and easy but it takes forever to install. I tried rebooting my phone but it just starts all over. The app still hasn't installed yet. I'm running out of memory on my phone but I deleted a lot of apps and emails and other things because I really want this app. That didn't seem to help. How can I make this work so this app can install?
