How to edit files on iPhone like iFile without a jailbreak?

There's no untethered jailbreak for my iPhone so I can't use iFile. Is there a software for my PC that I could use? One that actually works and connects with my iPhone via wire? I've used some software already but they can't connect to my iPhone.

Added (1). So far, no jailbreak for iPhone 4s with iOS 6.0.

Cut a regular sim down to a micro sim for iphone 4 and.its not working?

I was on my parents att plan with my iphone 4. My parents got pissed at me and decided to have my phone shut off. I went out and bought an att gophone to get me by until I decide to get on a plan myself. Well I found an article online explaining that I can use a gophone sim card in an iphone if I cut it down to micro sim size i just won't have 3g unless i change my APN settings so fine…

So I cut my sim card (it still works in the gophone although its difficult to get in there but the sim DOES still work)
I took out my iphones micro sim and inserted the gophone 'micro sim'
the iphone is giving me an 'Invalid sim' and a 'sim failure' message.
I have tried resetting network settings and rebooting with no success

I did cut the plastic slightly too small so it is a bit loose:\

What can I do here (if anything)?

Thanks… Really regret not going and getting a sim cutter

Why does my unlocked iPhone not work with my sim card?

I have family mobile (walmart phone service) and I trimmed my sim card to fit the micro sim card slot. I know that the iphone is reading my card because without it, it says no sim card but with it, it says no service on the top left corner. I already checked the Imei number and it said the phone was unlocked so I don't know what's wrong. I tried going on airplane mode then switching back. I tried turning the phone off and on and nothing is working. Could you tell me what could be wrong and how to fix it? If not, can you tell me where i need to go to get help (i.e.apple store, walmart, etc)

Added (1). Family mobile is a Walmart brand and is not the same as Straight Talk.

I did try and check the status of my phone and it said it was unlocked.

By the way, it's an iPhone 4s if that makes a difference.
