My Kik Messenger isn't working?

I have an iPhone 4S and about a week ago, the connection began to fail. I continue to receive incoming messages but I can't really look at them and if I reply it has the usual "." 3 dots that lets you know there's no connection reply back and then I get a "!" Exclamation point. At this point, I don't know what to do. Can anyone help?

Is it possible that Apple will release an Iphone 6s?

Apple has been doing that with all the recent generations, revealing a new 's' after the first batch.

I was considering of upgrading to an iphone 6 (this is not a question wherever I should get an iphone so please keep that opinion to yourself. I work around MacBooks and iMacs, it's only logical for me to have a phone that syncs) but I'm honestly scared that Apple will reveal a 's' of the iPhone 6.

It is rumoured that next month, only the 4.7inch iphone 6 will be released because they need to work long on the 5.5inch version, which is scheduled to release early 2015. Since they are revealing another version, only difference is size, next year, I'm hoping they won't be revealing a more 'newer' version of iphone 6. Rumoured that Apple is releasing an iphone air too.

So what are the probabilities?

Iphone 5 Icloud lock/restore mode?

I purchased an Iphone 5 on Ebay but had a question about I-cloud lock/restore mode. I haven't received the phone yet but it was listed "as is" in restore mode and I was wondering if restoring a phone is possible while it is i-cloud locked. I'm hoping that it isn't i-cloud locked and that i can finish the restore process and have an iphone 5 for cheap. The seller is a company that bought it from someone who brought it in in restore mode and they haven't tried to mess with it at all.
