Hi Alvin,

The error in that response tells me your signature is incorrect.
Double check you are generating your signature using the algorithm
described here:
    http://dev.twitter.com/auth#signing-requests

In particular I notice the parameters in your GET request are not in
lexicographical order, and so I wonder if they may not be in order in
your signature base string.

Best,
Matt
