Upload what kind of software? You cant just install whatever software you want, it still has to be iphone compatible.
Here's the issue - if you phone is NOT jailbroken, there's no way you can do this.
If your phone IS jailbroken, then you could install it via SSH/USB browser if, and only if the person who developed your app have it packaged into the correcty formatted DEB file format.
You'd need to find out these details first.
With respect Tramain, I dissagree with your choice to warn me. I made no such Discussion about pirated apps. Installous is a free application that you can use to install applications to your phone with. There are plenty of IPA's available on the Internet as freeware just as they are in the apple store. I wouldve replied elsewhere but I have yet to fufill the 15 post requirement.
It's also not fair that you cut my reply down without discussion. Abuse of powers.
