Like it says in my signature, I dropped my Eris in favor of the iPhone 4 (mostly due to the Eris' crappy battery life), now I still kept my Eris due to features on it that aren't available on the iPhone
Now I was told that I could simply shut off the iPhone, dial *228 opt 1 on the Eris, and my number and data plan would transfer to the Eris whenever I wanted, and vice versa when I wanted it back on the iPhone, and I know it should work, but it doesn't, when I attempt to do so, it first tells me that it is programming the phone like it's supposed to, followed by a message saying "sorry, we are unable to program your phone, goodbye" and the line disconnects, this is with the right phone number and SSN
I got fed up with trying to transfer the number, and never had a chance to go into a Verizon store (and whenever I did, I never had my Eris on me, though they all say it should be possible), that I just opted to use it as a serviceless tablet (like an Android version of an iPod Touch), I noticed that everything I wanted to keep the Eris for worked fine over WiFi, it was just the matter of finding a WiFi hotspot to connect to
Not long ago, I enabled the Hotspot feature on my iPhone, and noticed it worked very well with the Eris, and seemed to work flawlessly with Navigation, I am just afraid to leave the hotspot on for voice navigation and recalculating (which again works flawlessly if WiFi stays on)
Now what I am afraid of is I don't want to go over my 2GB hotspot pool just so I can use Navigation on my Eris, and on top of that, chances are if I am going to be using the iPhone's hotspot feature on my Eris, I am bound to be using it on my laptop too, using up quite a bit of data
My question is, how much data does the Android Navigation app use up? Am I right to worry how much bandwith I may use up when using the Hotspot feature? $20 for every additional GB I go over is a bit expensive IMHO
