Good review of a break through product.

Complete Sprint HTC EVO 4G specs and reviews

"So you've run out of room on the 8GB microSD card that came with your HTC EVO and just picked up a roomier 16GB or 32GB microSDHC so you can store more music, movies, and apps.

Unfortunately, you've already got lots of applications stored on the stock card (even ones that aren't supported to be there), as well as tons of pictures and music. The last thing you want is to lose all of that and start over from scratch.

Fortunately, moving everything to your new card and having it all work is an incredibly simple process that doesn't require anything you don't already have: 1) an EVO, 2) a computer, 3) a new SDHC card, and 4) tweezers (optional)."

Interesting stuff. Testing on Android now. 500 minutes free conference calling with overseas country connections!

Excellent discussion of CDMA based 3G, Sprint WiMAX 4G, and Verizon's VERY limited capacity GSM LTE.  Keep in mind that Verizon is today an exclusive CDMA+ shop.  They do not do GSM (AT&T, Apple and most of the rest of the world outside the USA).  No mention of T-Mobile who has introduced a very fast and thick CDMA+ that is faster than WiMAX.

excerpt: I'm hoping Apple expands beyond AT&T with Sprint instead of Verizon or, at least does what Samsung just did with the Galaxy S series — make an iPhone for all the major carriers.

Why should iPhone be on Sprint? Here's five reasons:

WiMAX (worldwide interoperability for microwave access) is a fourth-generation (4G) telecommunications technology primarily for fast broadband.

Also a 4G mobile technology, LTE allows a peak download speed of 100 megabits per second (Mbps) on mobile phones, compared with 20Mbps for 3G and 40Mbps for WiMAX.
“For operators, the choice of technology depends on a number of things including available spectrum, legacy inter-working, timing and business focus,” says Nokia Siemens Networks head of sub region, Asia South, Lars Biese.
To deploy either technology, operators will have to commit tens of billions of dollars in network upgrades for the new mobility landscape, which now includes social, video, location-based and entertainment applications and experiences.

Wing K. Lee says WiMAX and LTE more similiar than different.
Also a 4G mobile technology, LTE allows a peak download speed of 100 megabits per second (Mbps) on mobile phones, compared with 20Mbps for 3G and 40Mbps for WiMAX.

Some argue that LTE is the next step for mobile networks like GSM, WCDMA/HSPA and CDMA in the move to future networks and services.
The common belief is that the natural migration path is from 2G to GPRS, from GPRS to 3G, and from 3G to LTE.

But IDC Asia/Pacific’s telecom research director Bill Rojas has a differing view. To him, LTE is a totally new set-up.

It has been reported that LTE’s main advantage over WiMAX, in addition to speed, is that it is part of the popular GSM technology and can allow backward compatibility with both 2G and 3G networks. A point many dispute.  The new Sprint EVO is a 4G smartphone with chipsets for 2G, 3G, 3G enhanced, and 4G WiMAX.  Sprint argues that LTE is just another chipset away.
