My iPhone 3GS is automatically deleting text messages? - 1

I've had my iPhone for a few years, and it's never done this before. I have a conversation with one person that dates back to last summer. We've exchanged about 150 texts, and none of them have been deleted. But tonight, every time I sent a text, the oldest one would be automatically deleted. How can I fix this? (I jailbroke my phone 4 days ago, but I've texted this person twice since then, and nothing has been deleted before tonight)

What food should I be eating to help lose weight?

I'm trying to lose as much weight as I can over the next 18months for my wedding.
Health and fitness isn't really my area of expertise so I'm not really sure what I should and shouldn't be eating.
I do understand that I need to be eating my fruit and vege but what else can I eat?
I have been using an iPhone app to track my calories and have been coming in around 1200calories a day.
Is this too much/ not enough? I really have no idea what so ever.
Any advice would be brilliant.

My 4G On My iPhone 5 Sometimes Doesn't Work?

I love my iPhone, but sometimes the 4G will just shut off and either show an "E" (for EDGE). I know that I'm not out of range for reception because when I turn my iPhone off, then back on, I will get 4G again. Please tell me what I can do to fix this problem, It's IRRITATING!

How to transfer songs from iPhone to iTunes 11?

Just got a new computer with windows 7, and wanna transfer the songs off iPhone 4 to empty iTunes 11 library. I don't see the "transfer" songs button like the old iTunes, and when I plug it into my new computer, the option doesn't come up. And i've authorized the itunes already with my account.

Can you buy an iPhone 4s without a service plan? - 1

I recently broke my iPod touch, I cracked the screen completely, and it shattered, and then, I left it out in the rain, (i know, stupid) and now it won't turn on. Instead of buying a new one, or getting it repaired, I saw that you can get iPhone 4s really cheap out there lately, and so I thought I could just get an iPhone 4s instead. I have a phone currently, and I just got it in August, and I'm with the AT&T 2 year contract, so I can't buy it and use it as a phone. Can I buy a iPhone 4s, without a contract, plan, or data plan?

Thank you

Iphone data plan help? Please look?

Alright currently i can get an iphone 4s with no data restriction or an iphone 5 with 2 gbs of space a month. 100mb a day. I have no Wi-Fi yet but live on my 3g on my phone. I just would be on twitter, average browsing, and playing and installing apps. 2gb is straight talk, unlimited is virgin mobile.
