I've played on an iPod 1st generation and my current iPhone, so isn't much stress on any computer, I understand it lacks graphics and that but could it not live stream with the 8gb Ram and 4x4.2ghz

Skype not working? IPhone 5, iOS 8.3?

When I try to change my profile picture on the Skype app, this appears. However, in my settings, I can't find a fix. I went Setting > Privacy > Camera, but Skype doesn't appear as having requested access. So I tried Settings > Skype (as instructed by the Skype support site) but there was nothing there that helped, either.

Anyone know what I should try? I've already tried closing and reopening the app and doing a hard reboot of my phone.

Cheers in advance. Skype not working IPhone 5, iOS 8.3

Problem with Iphone 4s recovery?

You can skip this part, this is is not my main problem. // My dad gave me his old iphone 4s - ios 7 just yesterday (may 29th, 2015) & he has been using it since like 2013. I was so excited when I received it because it was the first iphone I've ever had in my entire life. So fast forward to may 30th, we were at the beach and I left my phone with my mom because I don't want it to get wet. Fast forward, my mom went close to the water and slipped at the big slippy stones under the water with the bag full of phones and bills. Everything inside the bag got soaked and my mom got a big scar on his knee. Okay this is getting longer, I'm going to my main problem.

**MY MAIN PROBLEM**
My phone survived (I think) because the screen still looks clear and when I went to charge it, an itunes logo and a charger thingy (sorry I do not know what's it called) appeared on the screen. So I went to itunes and it said that i need to recover/update my ios to reactivate my phone. But it would all erase the data etc. But that's not actually my problem. Its just I don't want to update it to ios 8.something because I know that it would get slower and my phone is already slow when running as an ios 7.

**MY MAIN QUESTION**
Can I skip recovery on my phone and get back all my data? I have tried recboot but it doesn't work for me. Can I use my phone like back to normal? Please help thank you so much. Just tell me all you know, maybe it could help. Thank you very much.

PS Sorry for my english.

Added (1). I don't want to get it fixed by local electricians because they want to get paid for like 400 pesos ($20, and yes it's a big deal for me)

How to get my messages back?

Hi, my 'friend' messaged me this stupid bug thing on message as we both have an iPhone which cause my phone to reset and my messages to me blocked… My iPad and phone are linked so she then messaged me on my phone with canceled the 'string of text' on my phone but because it was a text it didn't cancel it on my iPad. And now she isn't answering my calls or texts so I can't get her to message me to cancel it… Is there anything I can do to cancel this string of text so I can use my messages again?

Please help. Sorry if this doesn't make sense, thanks
