Testimonial from an existing user of SyncMeMobile - this service is excellent, and responsiveness for any technical issues/reactivations is top-notch. (As someone who is always futzing with latest OS versions, I have to request a lot of reactivations. Sorry, Geoff. But thanks for never giving me crap about it.
I highly recommend this for anyone looking for a hosted BES/Exchange solution - whether an individual or a small to mid-sized business.
