I just put together a comparison chart between the Sidekick 3 vs Blackberry 8100. If I made any mistakes and/or want to add something to my chart than please let me know. Thanks.

Just a couple things:

1. You can get a text messaging plan for the 8100 (T-Mo unlimited for $14.99)

2. The SK3 does NOT offer Bluetooth Stereo Headset capability. You cannot listen to MP3's through the bluetooth.

the pearl offers bluetooth headset capability?

*IMO-the sk3 is TERRRIBLE as a business/personal phone. The pearl is the best fone/pda I've ever used by far. I bought the sk3 brand new from ebay for $380, used it for a week and a half and now it's just sitting in my house. Im going to sell it soon. Its a great phone, if you're 18 and under and love texting and aim. Other then that, the other features are just "wannabe" bb features. again...my opinion.

I fully agree, I had the SK3 for 1 month. The minute I saw that T-Mo had the 8100 I sold my SK3 and bought the 8100 the same day. And yes, the pearl offers Bluetooth Headset capability, but not Bluetooth Stereo Headset. (You can't listen to music through the headset)

That's what I thought. It would've been nice to have that feature. working out without having wires attached would be awesome.

*another thing I ABSOLUTELY hated about the sk3....1.3mp camera? BS....more like 1.3pixels

t-mo's "minutes and mail" plans include unlimited data and text.

i'm pretty sure the sk3 can handle wap browsing.

you forgot to add video playback for the pearl.

also, most sk3 applications aren't free.

The blackberrry data plan does not include text messaging. You have to buy a text messaging plan seperately.

O yeah...i forgot to mention that I paid $5 for time traveler(an ALARM CLOCK) and $10 to sync my sk with outlook.

If you have the "Minutes & Mail" plan with unlimited Data, this includes text messages. In almost 3 years, I have never been charged extra for SMS.

A couple of amendments to the table:

-The SK has push email, but only for the tmail.com address you get with a SK.
-For multiple languages, the SK can display and write unicode. I've visited Japanese web sites and written IMs and emails in kanji and hiragana.

The table says that the 8100 does not inc a mem card... it does...

It does not include a memory card. It has built-in memory.

You may have an older plan that has been 'Gradfathered in'. However, if you were to start new service today with a minutes & mail plan, you would not get unlimited text (sms or mms) messaging. That's separate.

8100 has a Micro SD card actually (as well as 64mb built in memory)

Where????? There was no MicroSD card in the box!!!!!!

It doesn't

Must be uk then?

My 8100 has a 128mb MicroSD pre fitted.

I know, coz I've taken it out and seen it!

What carrier do you have???

It's an o2 device

Not quite sure what that means....

I have T-Mobile.
