How many gigabytes for 3500 songs?

I know it all depends on the length of the songs and everything, I have some long songs and some short ones and average ones. But my itunes has about 3500 total and my iphone is 16g so it won't take all the music, let alone my apps (which i don't have very much of). I'm thinking of getting an ipod with enough memory for 3500 songs and maybe more room for more songs in the future, is a 16g ipod too small of memory?

Where can i buy cheap iphone 5 clones/replicas?

I've been looking all over the internet and whether it is legal or not, i'm trying to look for some very cheap iphone 5 clones (usually from china or pakistan). But the problem is, i can't find a good website which you can actually buy from. Also i know for a fact that to make a clone it only costs £1 ($1) and they're asking for hundreds of bucks for one replica. Its rather annoying so if someone could help me then that'd be great.

Why isn't my iphone 4 receiving texts?

Both my boyfriend and other friends have told me that they've sent me numerous amounts of texts over the past two days but I haven't received any of them. They tried to call me and I received the phone calls perfectly, however, I also got my dad to text me to see if my phone was ok and his texts worked perfectly. Why wasn't I receiving other texts?
