Should I keep data roaming off on my iPhone?

Should I? I'm in my home country and currently utilising my Wi-Fi, which is the only time I usually access the Internet anyway. As long as my data roamings off that means I'm not paying ANYTHING right? So should I keep it off?

How does Ebay's free shipping work?

Do frequent Ebay sellers who offer free shipping in their product have some kind of UPS membership or plan where they can ship stuff for free? Or do they have to buy the shipping them self each time they send something?
I have A lot of iphone cases i want to sell and if the shipping cost more than the actual item i'm selling then I rather not sell anything.

People aren't getting my pics. Why?

Ok so I've got AT&T and I've got the iPhone 4. Picture messaging is part of my cell plan and I've always been able to send/receive. Well the past few days everyone I send a pic too doesn't get it. It sends perfectly fine. But they never get it. I can receive there's, but for some reason they never get mine even though it sends. They have to give me another number to send it and they get it on that number. So is it my phone or there phone?

Lowering dhcp lease time below 1 hour?

(Typed on iphone) Stay with me here. The default gateway (DG) lease time needs to be lowered to about 15 minutes maybe 30. The router only has a option to go down to a hour. So if you do know how to do this please comment. If not maybe you have a better solution.

(Longish story) the router I converted to a switch which I will refer to as RS is a 2wire router it's dhcp time is set to 24 hours and te router will not let me change it even with the password. But the RS updates the Lease time about every 30 minutes not 24hours. This changes the DNS server ip to its own instead of the DGs. (There's no way to disable the ip lease time from resetting on the RS router unlike the rest of the dhcp functions)

So my plan was to have the DG refresh the lease time before the RS. The only problem is even though the lease time on the RS is set to 24 it updates about every 30 minutes. While the DG only updates every hour.

If you know how to set the Lease time below 1 hour please respond. If you have a alternate theory or idea or solution please comment.
(Or if you do not have a solution idea or theory but you do think I'm crazy please comment) ( I would go and buy a 30 dollar switch but I'm 15 and my incomes low so I'd rather not)

What is the other space for iPhone iTunes memory?

What is the other space for iPhone iTunes memory?

There's music apps pictures then there's other. I can't figure it out, it takes up 2.5GB of my memory and I've erased so many things and that bar just doesn't go down.
