I can't understand your post.

Also, you may consider just taking care of your batteries in the future. Don't use them while they're plugged in, don't leave them plugged in for extended periods of time, don't charge them until they actually need to be charged, etc… You can also turn your brightness down, make sure bluetooth and Wi-Fi are off when they're not in use, turn off location services, etc.

Battery apps are nothing more then adjusting your settings, which you can do yourself.

  • Which wireless carrier you recommend below $50? I have Sprint service right now and the contract is expiring in Feb. I have iphone 4s with SIM card.So, I can switch to any GSM service too. I'm not a heavy data user (may be 500MB a month ) and use only approx. 700 minutes with text. Which wireless carrier you recommend? Suggest something below $50.

So I tried to reset my password from the computer, and it sent the email, but I must of put my twitter on a different email account than my usual one, and I can't remember which account it is. Or the password for my email. So basically, I can't get on the twitter I use elsewhere apart from my iPod, and my iPod has now broken. What do I do?
