FYI, my G1K has not locked up once and i have it overclocked. my old palms have locked up once or twice because of applications...

its also worht noting that the palm environment is not buggy as a whole.. its the converged device coupled with 3rd party hacks thats causes the problem.
the pda phones are more sensitive than a conventional palm device and this is the major reason for the lockups...

now...

as for your aircard issue, i have the sprint aircard and i use it everyday. what problems do you seem to be having? you can pm me off list if you desire....
