I bought an iPhone 3g last year in Switzerland (swisscom carrier). I use redsn0w and ultrasn0w to hacktivate and unlock the phone so that I can use it where I live (France). Problem : push notifications don't work very well on hacktivated iPhones (even with push fix released by dev team).
I am now looking for a swisscom sim card only for activation (like an empty prepaid sim card) and I would be very grateful if anyone can provide me one.

Thanks in advance.
