They did mention that as the cell towers and sofrware are upgradded, the new sim card will be needed to run at the higher speeds.

That's interesting. The guy I got mine from said they weren't sure if it would make any difference. Way to train you employees to be on the same page AT&T!

Form as much as they charge you would think that they would atleast train the help.

They are trained, but most either skip through the training and just take the tests until they pass it, or put off the training until the last day. At&t provides trainings in advance of all devices and changes.

They lied or didn't know what they were talking about. You can keep your unlimited but will need to change it to "Smartphone personal Unlimited", it has a different code in their system.

I came from a Blackberry and that's what they did. Search these forms and internet, you can keep the unlimited.

How would this work with an unlimited plan with other 3G phones on it? We wanted to add an Inspire to the account but they said we need an additional data plan for it, so we got the cheapest for $25. Could they just have switched all the phones over to the "Smartphone personal Unlimited" plan for free, and they're just taking us for a ride? Or does that plan only work with 4G phones?
Thanks.

Edit
I just did a search for "Smartphone personal Unlimited" and it seems like you'd only need to switch to that coming from a BlackBerry, otherwise you already have it. So if we already have the Smartphone personal unlimited plan, why couldn't they just add the Inspire as an additional line? Does it really need a separate data plan?

Every phone listed on a family plan will have a separate data plan. My wife and I have been using iPhones for quite some time now, but decided to try other phone the other day. I went with the Inspire 4G and kept everything on the rate/data plan the same on our family plan, but the data plan changed to the Smartphone personal Unlimited instead of the Unlimited iPhone data plan. Both phones on our family plan have separate data plans.

Bought 4 Inspires at once. 3 Would display "H+" and 1 constantly reported "E".

Took them in and demonstrated and the one that displayed "E" got its sim card replaced.

Poof > "H+"

Northeast Oklahoma, when 4G is said to not be available "consistantly" yet.

And the Modile network type reported on the phone is "HSDPA"

Why would it make a difference? The major air interface difference between HSDPA and HSPA+ are the higher code rates and larger number of wcdma spreading codes from the phone's point of view which are reported back to the tower by the handset as it's device category, so the tower knows not to attempt to transmit across more codes than the handset can despread or in a modulation scheme that the handset can't demodulate.

It doesn't make sense to store that information on a SIM card (and in other android phones it seems like it's a build property in the software and unrelated to the SIM) - such a sim card placed in a non HSPA+ phone (say you dropped your phone and broke it and swapped your SIM to a non HSPA+ backup phone) would result in the tower attempting to transmit data across more codes than the phone could receive and would result in what looks like garbled data from the tower. Storing the data internally at AT&T doesn't seem like the right choice either, when the phone roams to other HSPA+ networks those networks would still need to know what device category the handset is so their towers can configure the transmissions properly so that the handsets can "understand" them.

This is something AT&T needs to provide directly to the end user, the information on how towers will determine how to transmit data to the handset and how the towers know what the device category is.

I imagine the different SIM card is purely a marketing thing (don't put a sim that says 3G on it in a phone they're trying to sell as 4G), but if the SIM really does have something to do with it, that'd be really interesting to know.
