GrandCentral.comWe have a grip of GrandCentral invitations for all of you readers out there! GrandCentral is a free (during beta, at least) service for attaching multiple devices to the same phone number, along with a killer voicemail system. I’m not going to go into detail in this post, but it’s worth mentioning that GrandCentral is apparently the “Hottest Mobile App Ever.” How can you argue with that? Think switching to GrandCentral as the first part of your transplant to the GPhone.

Write to us in the comments for this post if you’d like to receive an invitation to GrandCentral. Also, we’d love to hear from you on what you want in future postings on GPhoneholic. Your opinion means a lot to us.

Keep watching GPhoneholic this week. We’ll show you how switch only your voicemail to GrandCentral (so you could continue to use your current cellphone number). Nobody who calls you will ever have to even know that you switched any services.
