RIM has announced their BlackBerry Push service will be undergoing maintenance tonight, this means the push service will not be available during this time. I hope this will solve all the issue we’ve been having lately (at least in the Caribbean). Here’s the tweet from the BlackBerryDev:

BlackBerry Push Service will undergo an upgrade tonight from 1 AM-5 AM EDT. Push infrastructure will not be accessible during this time.^MS
