請在手機上直接鍵入 *#0000# ，
就會跳出目前的軔體版本~
20070101前購入之版本應為2.0618.06.05，
目前可更新之版本為3.0633.09.04。
如果你已經是最新版本，那你就可以不用更新，
但是還是需要下載安裝NSU(NokiaSoftwareUpdater)，請看：
在你安裝了Nokia PC Suite最新版應該可以看到裡面多了一個ICON，
就是我圈起來的地方，用力給他按下去...
[以下為下載安裝NSU的程序，還不是更新喲~]
<Step1>連結回Nokia官方網站。(((這是英文版的，別怕!跟著我做就行了~)))
<Step2>選擇E61，按update via PC。
<Step3>step1/5，按next。
<Step4>step2/5=備份，在手機上按下[工具]>[記憶卡]，按左邊的[選項]，選擇"備份手機記憶體"。按next。
<Step5>step3/5=選擇語系，按下English，別擔心，更新時會判定為繁體中文的。
<Step6>跳出下載視窗，約21.8mb，儲存吧~
<Step7>step4/5=next。Step5/5=finish。
<Step8>執行剛剛下載的NSU安裝程式。
安裝好NSU以後，就要準備更新了：
(((每次更新，切記先備份，因為更新後，資料會全部刪除的。)))
Step1:將E61與電腦連接，切記中途不可斷線或關機，
Step2:按下電腦端套件的[更新手機軟體]，就會出現
Step3:更新過程約15分鐘，注意不要造成斷線或關機的危險即可~
Step4:更新過後重開機，在手機上再按下[工具]>[記憶卡]，按左邊的[選項]，選擇"從記憶卡還原"。
:::大功告成:::
日後還是可以透過NSU來進行手機軔體的昇級。
更新軔體的好處：
- UI的整體速度大幅加快
- 瀏覽器速度大幅加快
- M4E可以正常運作
- 不小心按到錄音鍵，會停留在錄音畫面等執行，不會自動執行錄音
- SMS發送速度加快 (有些人在前一版裝SMS accelator加快速度，在這一版已不需要，裝了效能也不會再加快）。
- 網路電話功能方面的修改
- NAT 支援（據說是SIP方面的支援）
- 較佳的 IMAP郵件支援
- ctrl+C 及 ctrl+V 可以使用
可能的風險：
- 記憶卡有可能被自動鎖住而且無法知道密碼 (((我沒有遇到)))
- 升級後有某些安裝的程式會被移除或無法執行，須重新安裝。問題不大！
- 某些安裝的應用程式須重新輸入註冊碼。 (((這是應該的吧!)))
