Treo 680 : différences entre mise à jour 1.12 et 2.12 ????

Bonjour à tous,

Il y a trois semaines j'ai mis à jour mon Treo 680 avec ce patch :
http://www.palm.com/us/support/downloads/treo680update/unlockedgsm.html

Aujourd'hui, je découvre ceci sur le site de Palm :
http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=EUPalmSupport,TS=PalmEU_UK,Case=Obj(11152)
(URL courte : http://tinyurl.com/26uhco)

La descriptions des deux mises à jour est identique :

---------
* Corporate email as it arrives¹ – Have your corporate email
delivered to you with Microsoft® Direct Push Technology. Accept or
decline meeting invites and access your company directory on the go.
* Power saving enhancements – Helps conserve battery life with
improved power management and updated default system power preferences.
* Supports larger expansion cards – Supports up to 4GB SD expansion
cards (including the SDHC format), sold separately.
* Enhanced ringtone support – MP3 and other sound files purchased
from the web or sent from friends can now be set as ringtones and alerts
(formats: MP3, AAC, AAC+, MIDI, WAV, and AMR). ²
* Three updates in one – This update incorporates three previously
released software updates: Treo 680 Camera Update (January 2007), Treo
680 Security Patch (May 2007), and Treo 680 Unlocked GSM smartphone SMS
Update (July 2007).
---------

Seul le n° de version diffère. Il y a une différence autre que ce n° de
version entre les deux mises à jour ?

Merci d'avance,

Charly
