To enjoy the service of Push E-mail Blackberry, users do not have to have a BlackBerry phone. The reason is now the BlackBerry Push Email applications can be applied in a non-BalckBerry phone, using the Blackberry Connect for Nokia. Mobile-phones that support this service are: Communicator 9300, 9500, and E90, and another Nokia E-Series (E50, E51, E61, E61i, E62, E65, and E70).

Its application and guidelines can be downloaded at http://www.businessoftware.nokia.com/blackberry_downloads.php

As for the steps as follows:
1.  Before you download the Blackberry Connect software, be sure to check the firmware 
    version of the Nokia mobile phone, (just type: * # 0000 #) e.g, for Nokia E61, the 
    version is: 3.0633.09.04, then downloaded to the BlackBerry Connect 4.0, version 
    7.45.0
2.  Download the software into your PC, then switch on the Nokia PC suite to install this 
    software into the Nokia E61.
3.  Once installed on the Nokia E61, it will create a folder on the BlackBerry menu. Open
    the folder, and select the Settings menu, then activate the BlackBerry service with
    changing the menu, and the BlackBerry service: ON
4.  After the BlackBerry service in the ON position and connected, then you can see the 
    PIN from Nokia Device menu info. PIN and IMEI are on record as it would be
    useful to be registered in BlackBerry Webclient (BWC) http://xl.blackberry.com/.
    Prior to registration in BWC, firstly do registration through the menu of Network
    Service Info> Host Routing and select the menu of Register Now. Then do
    registrations at BWC (full guide can be found in the Create New Account BB on this
    blog). Once registered on the BWC, you can make registration a few email accounts
    that will be entered into the  BlackBerry Connect for Nokia. Do not forget after adding
    emails account on the BWC, do the Send Service Books.
5.  If Service Books is successfully received in the Nokia E61, it will create each email
    folders into the Messaging menu
    Menu> BlackBerry> Settings> Service Info> Service Books

If all steps succeed, then the BlackBerry push email service on the Nokia E61 can be used. Ensure logo appears on the display of Nokia, as it means that it is connected with the server of RIM BlackBerry. However, if only half the logo appears or there is a slash in the logo, it means that it has not been yet connected with RIM's BlackBerry server, so the push mail service can not be used for these conditions.

Note: For another series of Nokia mobile phone, the process is almost the same.
If your BlackBerry is a type of Enterprise, it is necessary to do the following steps: Enterprise Activation, select menu> BlackBerry> Activation for registration of enterprise activation.
