Help me decide between 8310 n 8320

[Pabula]

Let me start by saying that this is my first BB, although in the past i have used Palms, this will be given to me from work.

Reading the specs, i only see a major difference
8310 has GPS but no WIFI
8320 has WIFI but not GPS

I live in guatemala, and it would great if i could use google maps for it as im gona travel a lot, i check google and the map is good enough for my usage as long as i can use it with either BB.

So here some questions to help me decide,

1) Does either BB need to conected to internet to use Google maps? or can they be downloaded to the BB and used without any internet?

2) If google maps can be dowloaded to a pc (a BB compatible version), would i be able to it to my BB via USB or bluetooth or do google maps need to be dl directly from the BB?

3) Would and extrenal GPS work with BB 8320 and google maps?

4) Can a BB 8320 work at the same time with an external GPS blue tooth aswell as with bluetooth headset?

5) I seen some people comment about using WIFI as an option for calling, is this a service provided by the phone company or is it more like VOIP thing?

Seems to me that the 8310 would fit better, as i dont think ill be web browsing to much, so WIFI isnt that big of a deal, but im still unsure if GPS will work in guatemala accuretly, so if this is the case i would prefer to end up with wifi and just use the google maps as maps without any tracking, but any answers that you guys can give me ill be very greatfull.

Thanks in advance for any advice or answers, i also apologize for my writing, as english isnt my first/native language.

I'll try and answer some questions... someone will chime in and correct me if necessary...

First, I believe you do need a data plan for Google Maps... you cannot download the maps to your phone.

You can use an external Bluetooth puck. I use the Freedom Keychain Puck, and I am very, very pleased with it.

I have paired my headset and the Freedom puck at the same time. I use TeleNav software, and when making a call, the software pauses (I don't get any voice directions. Both devices do pair with it though, so I think it might be a TeleNav thing.

Wifi calling on the 8320 is optimized for Tmo here... I don't think it supports Voip.

For the reasons you gave, I would go with an 8310... I decided on the 8320 because wanted the wi-fi, and I knew the puck would make the device close to perfect.

For someone who isn't a native English speaker, you are phenomenal!
