A dilemma: an Iphone or an Ipad Mini?

I had an iPad Mini for about two days and I absolutely loved it, but I had to return it for some reason. However, my contract for my phone ends pretty soon so I will have to get a new phone. An iPhone is an option but if I get it, I would use it to browse the Internet a LOT. If there's a new iPhone released like iPhone 6 or something like that, I can always upgrade it.

However, the screen is small and I will have to keep making monthly payments to support the data usage for iPhone. On the other hand, I can buy an iPad Mini with Retina Display (and I can get any phone that I don't care about) but my biggest concern is that, what if Apple releases another new iPad mini and the money I just spent on buying my current iPad has gone to waste?

Why did he give me his password?

So my friends and I went on a roadtrip and my guy friend was sitting right behind me and he only told me his password and his best friend. But he knew this other girl longer than he knew me and she kinda got jealous when he told me but I'm really curious why did he give me his iPhone password

Any idea when the iPhone 6 will be coming out?

I currently have the 4s and am due for an upgrade. Want to skip the 5s and wait for the 6 unless it's going to be while. I heard June - October. October may be too long to wait. The battery life on my phone is terrible and ready for a new one.
Thanks in advance.

Added (1). Exactly "Artv", I'm just guessing but people out there in the world of technology may have heard something I haven't. Didn't think it hurt to ask. I'm a grown, mature adult and don't have time to ask random questions for the heck of it. You shouldn't of wasted your time for your wise *** answer.

How to find out your cellular data username on iPhone?

When I first got my iPhone and put my sim in, I got a message from O2 telling me what my cellular information was
The other day I took my sim out to test an orange sim for my brother but it has reset my cellular data information, when I put my O2 sim back in I did not revive another message so I can't turn my 3G back on. I tried resetting my phone and resetting the cellular data information again.
Is there any number I can message to get the text from O2 again?

How to get money back from Colleague?

Two weeks ago a colleague from other department (Our company has 400 employees and I don't need to work with him) posted an ad on our company's internal website looking for a used iPhone. I happened to have one for sale and I emailed him. He came to my desk and agreed on the price $150. He also asked if he could try it for a day to see if it's suitable for him. And I agreed as I thought that's reasonable if he had a few options.

The other day I asked him if the phone is OK. He said everything is fine and he is going to pay me the same day. That was a Friday. He didn't show up that day. Then after the weekend, on Monday I sent him email asking him again. He said he was busy but he is going to pay in the afternoon. Again he didn't come. On Wednesday I asked him why he didn't show up. He said he was sick and he is going to pay on that day. It have been a few times he promised to pay but never came. It has been two weeks. I didn't want to go to his office to ask for money as I don't want to interfere the people in his office with their works.

So how can I get my money back? Will HR normally take care of personal issues(it happened inside the company though) like this? Or should I talk with his manager?

Added (1). So if it's still my property, and he is keeping my property with the intention of depriving my owner permanently of its possession. Can I say this is theft and talk with HR?
