My data on my iPhone won't work?

Basically I have the iPhone 4 and I topped up (I'm on pay as you go) and I got free data, mins, and texts, I'm on Vodafone and my data won't work out of house! At home I used my Wi-Fi but my texts and mins work. I already have tried texting web to 40127 but then they say update your settings which I already have done. And on my settings I have looked everywhere my carrier is on mobile network is on and everything. I tried to ring Vodafone but they said I need 3 to 5p which I don't have on my phone? Anyone got a FREE Vodafone helpline number I can ring of this phone? Not 2345 or 191. Thanks for any help I just want my data working, btw this happened to my previous android phone but then I updated my settings and it worked, why isn't it workin on this iphone? Wha am I doing wrong?

Can't download apps with 3G network?

I have an iPhone 4 with the latest up to date iOS software (iOS 7.1.2 or something like that.) I have straight talk with unlimited 3G data, talk, and text. At first, I loved it! I could download any apps and update them or whatever. Now I try to download apps and it says "loading" for a long time then says "unable to download app". It's even happening with small apps like i tried downloading an app the other day that was like 5mb and it wouldn't download. I can download over Wi-Fi though. I've tried restarting my phone and everything. I called apple and they said its probably my carrier so I called straight talk and they couldn't figure it out either. Anyone know what's happening?

IPhone 4 getting really hot, just replaced battery and still really hot?

I have an iPhone 4 and I have been having issues with it for a while now. It will get really hot (to the point where I can barely even touch it) and won't hold a charge. It's done this to me a couple of times. It fixed itself once, another time, I deleted my email account off of it and it was fixed… But this time, nothing is working. I've closed any opened apps, deleted my email, just got a brand new battery put in a few minutes ago. I just plugged it in and it's incredibly hot again and still not charging.

What's wrong with it? It my $500 or whatever phone just garbage now? Like… Ffs. I used to pay $80 for a flip phone that'd last me years… This is bunk.

I dropped my iphone 5s in the toilet? - 1

I dropped my iphone 5s in the toilet while i was at my aunties house and i grabbed it as soon as it fell in, i tried to switch it on and it did but there was a blue and a red line on the left side of the screen, i dried the phone with a towel and then we put it on a bowl of rice, my aunty took it out the next morning and then put it in the oven on very low heat for a couple minutes and then we put it back in the rice, we left it there for over 48 hours then took it out to see if it would turn on and it didn't so we put it back in the rice for another day and it turned on and was working fine though there was was a water mark on the top left side so we put it back for another day and then after that it would go to the apple logo then turn off and keep repeating that what should i do now?
