Push Registry not working on nokia N86 after rebooting the phone; works on N97 and Expressmusic

I have written a simple midlet that invokes itself after a socket connection from a server program. I am using Push Registry to do this. It works fine on all the test phones I have immediately after installing. but if I reboot the phone, the push registry stops working on N86 whereas it is working on the other test phones that I have viz. N97 and ExpressMusic 58开发者_高级运维00. Has anyone faced such a problem before? Any kind of help will be appreciated.

btw, after going a little deep into the specifications of these phones, I found out that though all the phones are MIDP 2.1, N86 has Symbian OS v9.3 and the rest two have v9.4. Can that be the reason for the behavior of N86 ?

I did a hard reset (press *#7370#) on the phone (N86) and everything is working properly! I still don't know what the problem was!
