Iphone - Which program can I use to transfer and modify txt files?

I have Iphone 4s, and I've jailbroken them. Now, I work with lots of txt files, and I would like to know if there are any programs which allows me to edit my txt files which I transfer from my computer to my iphone. Actually, I've found several programs that allows me to edit txt files (according to the application description), but I had a hard time transferring from my computer to iphone. Typicall, I use DiskAid, and I just drag and drop files into the application. Unfortunately, all the programs I've come across did not allow such methods (either the applications don't even show up in DiskAid, or the txt files that transferred don't show up when I open the applications in my iphone).

ITunes isn't accepting my debit card but it used to?

My iPhone recently began asking me to enter my debit card details when I'm on iTunes and the APP store… It used to work just fine but even when I enter my security number correctly and all of the other information is correct, apple won't accept it?

I'm with Lloyds

I want an iphone but I don't wanna have to get a data plan and pay like $100 a month with Verizon! So i was wanna get a used one off ebay then get a little mobile hot spot thing from Virgin Mobile (http://www.virginmobileusa.com/mobile-broadband/mifi-2200.html) and only pay $35 a month and call? Text with this app (http://itunes.apple.com/us/app/text-free-real-phone-number/id470580739?mt=8) called textfree! So would I be able to do it or not?

I inhaled air duster in a can

What Happened was my dad bought this at radio shack and was using it to get water out of his iPhone. So I thought cool I finally have something to clean my xbox 360 off with. The insides that is. Little did I know the dangers it has. I sprayed it in my room for about 17 seconds and then I was like wait can this cause cancer so then I began freaking out and looked online at kids who inhaled it and died. I just want to get rid of it now. The gas used in it was called Difluorethane. It was no Ozone depleting moisture free gas. I opened my window turned on the air conditioner and left the room but i did breath in the room when I was doing it and for about 15 seconds afterwards maybe longer. I'm extremely worried.
I think i did the best thing I could do. Also if you could tell me if there any such thing as oxygen in a can why not use oxygen, pressurized oxygen or if there's any mini blowers that sucks in air and pushes ut out like a reverse vacuums only small so it can fit in my xbox. Thanks and next time I will think twice before I spray death in a can.

Will an iPhone 4g SILICONE (soft) case fit in an iPod Touch 4th gen?

I want to buy this: http://www.aliexpress.com/...85921.html

It says this:
Compatible With: For ipod touch4
THEN on the bottom:
Compatibility with Apple iPhone 4 & 4s

It's very confusing and I want to know if anyone has ever bought this for an ipod touch? Or has bought an item similar to this and it worked for your ipod touch? I feel like it won't work for my ipod touch 4th gen cause it keeps on saying it fits on iPhone 4g as well and aren't they completely different size and shapes?
