T-Mobile, Samsung and T-609 phone

The problem: Samsung SGH-T609 phone from T-Mobile has no permission for accessing network from under the Java virtual machine (JVM). Only non-networked applets are working. GMail applet (as well as Google Mobile Maps applet) terminates with "network permission required" error message.

Research log:
- called T-Mobile 611 and was transfered to Samsung Technical Support (TS)
- Samsung technical support refered me to Level 2 TS
- Level 2 TS asked for IMEI (keypad code *#06#) and explained that JVM implementation on this particular model (as well as the whole line of other non-expensive models from Samsung) does not have network capabilities at all due to limited computing resources like CPU speed and available memory. PDA and smartphones has fully-featured implementation of JVM.

Please see another draft that lists service codes and links to relevant discussions: http://sanzay-ideas.blogspot.com/2006/11/setting-network-access-permissions-on.html

Conclusion: May be it is neither T-Mobile's nor Samsung's crippling of functionality nor it is a "signed code" problem... There is possibility that some phones just have lightweight AKA simplified version of JVM built in.
