is there any software that will let me send a full game or app i have installed on my 7650 to another 7650 via infra red or bluetooth
cheers

No.
You could try sending 1file at time with some file explorer, but those wont work (easily).

And besides, why ? :-?

found software that lets me do it . called (forward)
and the reason being i have a few mates who got a 7650 but no pc so i can send em to my phone via ir and then to there phone when im meet up with em
cheers

very easy if you keep the installation .sis file in your inbox. just send by bluetooth / ir / e-mail.
or just e-mail them the file from your p.c. to their pop3/imap account on their phone. :D
