Not to sound pretentious or anything, but I would expect two months to be enough for an experienced developer to get aclimated to a new environment and start being very productive. If you oversold yourself on your resume then I'm sorry to say that its your own fault. If on the other hand they were aware of your lack of experience in their particular methodologies and platforms, but still offered you the job, then it strikes me as strange that they wouldn't mentor you further, expecting you to slowly "grow into" the team.
