Not that I've seen. The promised firmware update is LONG overdue. I got this thing to be able to access some work stuff that is behind a PPTP VPN, which the SCH-LC11 is not compatible with currently. The webpage I bought it from said "VPN Compatible" so it's pretty disappointing. Are you having a different problem?
Samsung has an update which says it corrects connection issues. It does not say if the update will work on Win7 64bit. Verizon support told me to contact Samsung, who told me to ask Verizon. If I learn more about the update I will email you. I'm not about to post any solution which can be read by Verizon or Samsung.
