No I donít think there could be some way as well through which you can install those application to your mobile without using this software. But the thing that I am not getting is like what is the problem using such software? In fact thatís quite good way to install the application this way as youíll get any problem with those application ever.
And as far as third party applications are concerned, I would always recommend you that you should not make use of those applications in the phone until and unless there isnít any way left instead of that. Because they are the only reason can cause different problem with the phone.
