I want to buy a Verizon Android phone in the next few months and am very interested in the Eris but wanted the Google navigation. Now that the update has been announced would there be any difference in buying the current Eris now and getting the update when it comes out.
Or would it be better to wait and get an Eris that is sold after the update?
I don't see what any benefit to waiting would be. HTC will make the update available for Verizon to push via an over the air update. From what I've read HTC is making sure everything works right with Eris, 2/2.1 & Sense UI before they release it.
So if you want Google Nav you'll have to wait anyway but why not get the Eris now, get familiar with it and enjoy the Nav when the update comes out. I bought my Eris knowing it would get updated soon, love the phone, looking forward to it being even better once the upgrade hits.
