Using unlocked 3 mifi with foreign SIM's

Techn

I plan on getting the 3 huawei e585 mifi device when traveling to australia, new zealand and the USA.

Does anyone have experience doing this, or can offer info on the best SIM offers and companies to use?
Obviously the device will need to be unlocked, but i have all the info i need to do this myself.

This is the info i have collected so far:
Australia:
Telstra, pre-paid micro sim comes with 3gb data usage $30 (micro sim adaptor would be needed).
http://www.telstra.com.au/shop/Consumer/NGTSOProductDetailsView?catalogId=10101&storeId=10001&productId=88717&langId=-1&categoryId=29101&parent_category_rn=29101&top_category=&SMIDENTITY=NO

New zealand:
2degrees value packs, $20 for 1gb. Though only in 4 major cities.

Telecom SIM, $30, you get $10 credit plus and extra $10 for registering online. you then get 10mb a day for $1 that day.

USA:
This i'm less sure of, the only choice is T-mobile or AT&T.
T-mobile offer a web day pass on prepaid sims i believe, for only $1.5 you get unlimited mobile internet use for 24 hours, however could this be used in the e585?

Could you get this $20 SIM and make use of the deal?

As far as i'm away the e585 is quad band and could accept these sims, i believe it uses EDGE / GPRS / GSM 850/900/1800/1900 Mhz HSDPA/3G:2100 Mhz

If anyone has any other suggestions please do share.

Used Virgin/Optus for OZ, as the SIM(a normal sized one) was only AU$10. Micro is AU$5. Both are supplied with 300MB(though it may have been 500MB when I purchased).

Was ok for me as I wasn't backpacking for months. Was just using to research and book hotels and car hire....and some banking.

Also, bear in mind that Telstra have 3G on two frequencies. The one compatible with your device will be phased out of their network by January 2012.
Then they will operate only on UMTS 850. They call it their NEXT G network.

thats interesting, is there any noticeable differences in performance between the two?

i'll only be there for a month so should be ok, seems cheaper than paying for hostel internet (globalgossip it seems)

Lower frequency should have better signal penetration into buildings.
